About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X200-20S
The AirTAC SAIJ160X200-20-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 180-200 mm, allowing you to dial back the 200 mm nominal stroke by up to 20 mm during commissioning. Operating at 0.5 MPa, it delivers a robust 10053 N pull force, making it ideal for heavy-duty positioning.
This large-bore actuator uses a sturdy 40 mm carbon steel rod with an M36x2 thread, handling high side loads while maintaining a 30-500 mm/s speed range. The extruded aluminum barrel includes dual sensor grooves for CMSE reed and DMSE electronic switches. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X200-20S Is Used
Heavy Pressing
Dial in the exact 180-200 mm end position for high-force pressing and forming operations during machine setup.
Line Changeover
Quickly adjust the retract stop by up to 20 mm to accommodate new product sizes without changing the cylinder.
Assembly Stations
Provides reliable 10053 N pull force for heavy component assembly, with DMSE sensors tracking position.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X200-20S the Right Cylinder?
Select this 160 mm bore actuator when you need extreme force in a compact footprint, delivering 10053 N pull at 0.5 MPa. If your application requires less thrust, stepping down to the 125 mm bore yields 5734 N pull. The 20 mm rear adjuster allows fine-tuning the end position without adding external stops, unlike a fixed-stroke SAI cylinder.
For ISO 15552 replacement matching, verify the 160 mm bore, 200 mm stroke, 20 mm adjustment, PT tapered ports, and the -S magnet. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series. Even with the 40 mm rod, a 200 mm stroke benefits from an external guide to prevent side-load wear.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ160 Adjustable Cylinder SAIJ160X200-20S FAQ
At 0.5 MPa, it provides 10053 N pull and 14074 N push. At 0.7 MPa, the push increases to 14074 N.
The rear adjuster acts as an external stop, letting you trim the 200 mm stroke back to a minimum of 180 mm. It is a stop, not a lock, and will not hold the load without air pressure.
